Filed: 1991-09-13
Abstract: PURPOSE:To attain coding by both the mu rules and the A rules by providing shift circuits 6f 3-stage configuration, a control circuit controlling the shift width of a quantization code of an input nonlinear code, a subtractor subtracting 32 from a minuend, and a multiplexer to the decoding circuit. CONSTITUTION:The decoding circuit is provided with a control circuit 15 receiving a selection signal 14 used to select the mu rules or the A rules and a segment code of an input nonlinear code to generate control signals C1, C2, three shift circuits 11-13 shifting the quantization code based on the segment code and the control signals C1, C2, a subtractor 16 subtracting 32 from a minuend, and a multiplexer 17 selecting either the subtractor output or the shift circuit output and outputting the selected signal. In this case, the selection signal 14 used to select the mu rules or the A rules selects the mu rules when the signal is, e.g. 0 and selects the A rules when the signal is 1. Thus, the nonlinear decoding based on the mu rules and the A rules in compliance with the CCITT recommendations G.711 is realized by adding a small scale circuit to the circuit realizing either of both rules.

When a through-hole 5 is generated on the wall surface when high temperature gas 3 is loaded to the back 1b of the wall surface by applying pressure, the high temperature gas 3 passes through the through-hole 5 and leaks out to the front 1a of the wall surface 1. On the other hand, the front 1a is cooled by vaporized latent heat, when the water 2 evaporates. While the evaporation of the water 2 is continued, a state that a temperature is fallen in shown. Therefore, between the part of the through-hole 5 of the front 1a of the wall surface 1 and other part, a large temperature difference is generated, and by its temperature difference, the through-hole 5 is discriminated from the front 1a of the wall surface 1 and sensed by an infrared-ray camera 4. Accordingly, when the front 1a of the wall surface 1 is photographed by the infrared-ray camera 4 in such a state, the through-hole 5 is detected as an infrared-ray image.

CONSTITUTION:When the partial pressure of the carbon dioxide in the gas fed to the cathode side of a fused carbonate type fuel cell. is less than 0.1kg/cm<2>, the growing speed of the lithium aluminate particles is made higher too much, and when it exceeds 0.4 kg/cm<2>, the solution of the cathode is made larger too much to generate a trouble practically, and the fuel cell is operated in the scope of the partial pressure 0.1 to 0.4kg/cm<2>. The solubility of a nickel oxide to the electrolyte can be controlled less than about 5 ppm.wt., and the specific surface area of the lithium aluminate particles can be maintained at the value 8m<2>/g or higher even though some 3000 hours pass. This scope of partial pressure is favorable to apply even in the time no fuel gas is fed, because the growth of lithium aluminate particles is promoted in the condition same as in the operating time.

Title: Manufacture of plastic shield plate
Inventor: MIYAZAKI TAKAO
IPC: C23C4/10
Filed: 1991-09-17
Abstract: PURPOSE:To obtain a plastic shield plate where a flame-sprayed zinc particle cannot be released as one means against spurious noise by shielding an enclosure by performing sandblast onto a plastic plate with an alumina material and then performing flame-spraying of zinc. CONSTITUTION:A sandblast treatment with an alumina material is performed to one side of a plastic plate 1. An air pressure, a spray time, and an alumina particle diameter are preset so that a surface roughness of the plastic plate is 15-20 microns larger than a particle diameter of zinc at the time of flame- spraying of zinc. Then, flame-spraying of zinc is performed onto a blast surface 5 of the plastic plate subjected to sandblast treatment. A large current is made to reflow between the two zinc wires and a high compressed air is jetted to the melted material from a distance 30-50cm away from a target. The plastic surface 5 after sandblasting is roughened to 15-20 microns, thus enabling a zinc particle 4 to be adhered onto surface recessed and projecting parts and obtaining an improved adhesion property.
